100 microwatts isn’t much.<p>I’m curious how long other comparable batteries would last if you were only drawing 100 microwatts from them. I’m curious what you could run on that little power.<p>But I guess something a bit larger could probably be batteries in a smoke alarm, or other home security sensors? Idk how much power those draw but if it’s just making a WiFi ping sporadically it probably isnt much.
Clickbait BS:<p>"If approved for use in devices like smartphones, future generations of the battery would ultimately remove the need to ever charge them, company representatives said."<p>The battery is around a cube centimetre , a microampere is 1 / 1'000'000 of Ampere (A), a smartphone needs between 2 and 3.5 Ah , even a single LED needs milliamperes ( 1 / 1000 of A), you can do the math. Still this crap is reposted again, again and again. At this point I'm sure, it is part of a campaign to deceive investors. Two companies tried to collect funds for this kind of batteries, one simply disappeared, the other is under investigation for fraud:<p><a href="https://www.youtube.com/watch?v=5M5MF6KE-jY" rel="nofollow">https://www.youtube.com/watch?v=5M5MF6KE-jY</a><p>Anyway, what is the point of a 50 years battery to put inside devices people throw away after 4-5 years, top ? To produce more nuclear wastes in a world where people can't build nuclear dump sites ? It's hilarious if you think about it: apparently the same people that are against nuclear power plants, a technology able to save the planet reducing the fossil fuels consumption, find acceptable to put a nuclear source near their crouch to avoid phone recharges.
> Betavolt's battery sandwiches the radioactive nickel between two ultrathin plates of diamond,<p>What is the boundary for something to be called a plate of diamond vs a plate of carbon?
